Color is an attribute of visual perception and can be an important factor that affects the preference of customers toward bamboo and wood products. Solar radiation can discolor bamboo surfaces and initiate cracking. The purpose of this study is to investigate the effects of an ultraviolet (UV)-protective coating on the photodiscoloration of untreated and heat-treated Phyllostachys bambusoides bamboo surfaces. Artificial UVA radiators are set at a UVA irradiance of 2,000 W/m² to accelerate the aging of the outer surfaces of hot-air-dried and heat-treated bamboo samples. Half of the samples are coated with transparent UV-protective paint. As the UVA radiation progresses, the discoloration prevention efficiency (DPE) of the UV-protective coating on all samples decreases gradually. The DPEs of the hot-air-dried samples are estimated to be 31.4% and 18.8% after 21 and 72 hours of artificial UVA radiation, respectively. The heat-treated samples exhibit similar trends (29.0% after 21 hours and 10.3% after 72 hours). Recoating the UV-protective paint periodically every six months is expected to minimize the discoloration of the bamboo's outer surface.

With the rising importance placed on sustainability for brands, a plethora of research addresses consumer responses concerning eco-friendly products. While positive effects of eco-friendly traits on beauty products have been discussed, this study addresses a wide research gap in the makeup category. Based on the goal-attribute theory and the lay theory of ethicality, detrimental effects of eco-friendly ingredient claims on perceived appearance enhancement attributes (AEA) were examined. A between-subject, single-factor (eco-friendly ingredient claims present vs. absent) web-based experimental design tested the effect of conditions on makeup products that emphasized AEA. Results found a negative effect of eco-friendly ingredient claims on perceived AEA, supporting previous literature regarding the 'green gap'. Evidence showed that perceived AEA fully mediated the effect of eco-friendly claims on purchase intention, which was moderated by AEA preference. Interestingly, findings show that the purchase intention of respondents with a near-average preference for AEA was not moderated. Results contribute to preexisting literature by extending the lay theory of ethicality and product function mismatch to the field of makeup. Managerial implications are discussed, including opportunities for eco-friendly makeup products to appeal to alternative benefits.

This study aimed to elucidate the relationship between the selection attributes and visit motivations of Ningxia wineries and tourist satisfaction and intention to revisit. Utilizing multiple linear regression and simple linear regression models, the study quantitatively analyzed tourists' selection attributes and visit motivations for Ningxia wineries. Factor analysis categorized 12 visit motivation variables into four factors: 'Sensation', 'Educational', 'Companion-Friendly', and 'Experiential'. Additionally, 17 selection attribute variables were classified into four factors: 'Service Quality', 'Environmental', 'Facility', and 'Economic'. Through analyzing the impact of visit motivations on satisfaction and revisit intentions, we have identified the pivotal factors as 'Wine Cultural Education', 'Enhanced Companion-Friendliness', and 'Wine Cultural Experience'. In the analysis of the relationship between selection attributes and revisit intentions, crucial elements involve 'Service Quality provided by the winery"'and 'Environmental of the winery'. Conversely, key influencing revisit intentions include 'Environmental of the winery' and 'Costs and Pricing associated with winery visits'. To ensure the sustainable development of the Ningxia winery industry and promote the enduring growth of rural economies, wineries should place greater emphasis on cultivating wine cultural experiences, artisanal activities, and other project endeavors.

This study judged that although milk with various properties is currently being released, the growth rate of the milk market has not changed significantly, and the reason for this is that a substitution relationship has been formed between existing white milk and milk with various properties and they are competing with each other. The purpose of this study was to provide implications for the future growth of the milk market by identifying the relationship between diversified milk attributes. As a research method for this purpose the own price elasticity, cross-price elasticity, and expenditure elasticity of each attribute were derived through the LA/AIDS demand system model, and an analysis of consumers' milk purchasing factors was conducted through factor analysis. Based on the analysis results, it presented implications for growth in the milk market, such as expanding products with great differentiation in attributes such as flavor, plant and lactose-free properties, establishment of marketing strategies targeting consumers with children, and expansion of online malls.

This study analyzes the influence factors on elderly pedestrian accident. Elderly people are easy to be badly injured by car accidents compared to younger people. Therefore, various plans and measures are required to protect elderly pedestrian from accidents. However, pedestrian accidents studies only focused on microscopic factors such as attribute of driver, pedestrian, road design. In order to prevent pedestrian accident and reduce the severity of the accident, not only microscopic factors but macroscopic variables such as urban planning and facility should be considered. In this regard, this study develops an ordered probit model introduced the characteristics of urban facility which were not considered in the previous studies. The result shows that there is higher level of accident severity in such areas as large commercial area, well-developed area with transportation infrastructure service and non-pedestrian safety zone. Thus, various and appropriate countermeasures should be prepared in order that pedestrian accident can be prevented in the areas mentioned above. In addition to the aforementioned variables, it is revealed that other variables including vehicle speed, gender and age of pedestrian, weather condition, type of vehicle, etc. partly affect the severity of pedestrian accident.

This study investigates how bioecological variables affect the child's multiple intelligence through independent and interactional ways. The subjects of this study were 147 pairs of 5-year-old children and their mothers, and the Project Spectrum was employed to measure multiple intelligences. Each mothers was asked to answer a questionnaire on her child's temperament, her maternal parenting style, 'goodness of fit' and 'the fit of child's intelligence'. Data were analyzed using a factor analysis and a hierarchical multiple regression with SPSS WIN 15.0. The main findings were as followings; First, 'the goodness of fit' to the child's temperament moderated the effect of a maternal parenting style that would foster child's dependency on the mathematical intelligence through interaction. 'The fit of child's intelligence' also moderated the effect of maternal positive parenting style to the child's mathematical intelligence. Second, in language intelligence, girls were more verbally intelligent than boys. In that regard, because the sex variable entails a combination of both inherent attribute and social-cultural effects, that result can be interpreted as an interaction between the individual and the environment. Lastly, a maternal parenting style that would foster child's dependency moderated the effect of the child's regular temperament on interpersonal intelligence. This means that the child's regular temperament can be a protective factor for the negative effect of a maternal parenting style that would foster child's dependency This study suggests that interactional factors such as 'goodness of fit' should be considered in studies involving children.

The purpose of this study was to investigate the differences of histochemical characteristics in inflammatory fibrous gingival hyperplasia (FGH), phenytoin-induced gingival hyperplasia(PIGH), idiopathic gingival hyperplasia(IDGH) and control groups (healthy and inflammatory gingiva) by immunohistochemical method with various antibodies and histomorphological analysis. In immunohistochemical finding, antibodies to inflammatory cells (T/B lymphocytes, macrophages, other monocytes), proliferating cell nuclear antigen(PCNA), epidermal growth factor(EGF), factor VIII, and type I collagen were used. 1. The inflammatory infiltrates in FGH were less than those in inflammatory gingiva. The composition of inflammatory cells of PIGH was similar with that of FGH. IDGH showed a similar histologic findings with healthy gingival tissue. 2. In FGH, the number of fibroblasts and newly-formed collagen fibers was increased. No significant increase of fibroblasts and the dense accumulation of thick collagen fibers were seen in PIGH. The increase of fibroblasts and the dense accumulation of thick collagen were seen in IDGH. 3. PCNA-positive cells were localized mainly in the area accumulated with inflammatory cells and blood vessels, significantly increased in all hyperplastic tissue groups, and distributed evenly in IDGH. 4. The distribution of EGF were not observed in healthy gingiva but detected locally in area with confluent blood vessels,without significant difference between the other tissue groups. This results suggest that inflammation plays a significant role in inducing hyperplastic change of gingival tissue. While in DIGH, drug itself as well as inflammation seems to attribute to hyperplastic change.

'색채는 우리의 의식과 상관없이 긍정적 혹은 부정적으로 우리에게 영향을 미치는 에너지이다.' 라고 이텐(Johannes Itten)은 말했다. 우리가 자연에서 보는 색채는 감정에 우선적으로 강하게 작용한다. 이러한 색채의 경험은 우리에게 상징 또는 도상으로 다가오며 인간의 심리를 알레고리로 표현하게 된다. 애니메이션의 색채는 영상매체가 갖는 시각적인 요소이자 중요한 의미작용을 하는 이미지이며 빛의 속성이자 가장 먼저 눈에 들어오는 시지각적 요소이다. 형태, 움직임, 명암 등과 같은 조형요소와 함께 색채는 인간과 인간 주변의 상황을 표현하는 매체로서의 중요한 기능을 한다. 애니메이션에서는 캐릭터의 심리적 변화 상태뿐만 아니라 처한 상황을 암시하기 위하여 색채를 상징적으로 사용한다. 심리적 의미전달은 색채의 상징성을 도상(icon)적으로 표현하게 된다. 따라서 애니메이션의 이미지 표현을 위한 색채는 의미전달을 위한 보편성을 띠게 된다. 본 연구는 색채의 상징적 의미가 작품에 어떻게 반영되었는가에 초점을 맞추었다.

본 연구는 수학 학습에서 우리나라 학생들의 정의적 특성을 요인 분석과 인지 진단이론을 바탕으로 학교급과 성별에 따라 분석하였다. 이종희 외 6명(2011)이 개발한 정의적 성취 검사도구를 학교급별로 적용했을 때 요인 분석과 인지 진단 이론의 모델은 적합한 것으로 판명되었으며, 이에 따라 학교급과 성별 차이를 살펴보았다. 요인 분석에 의해 수치화된 정의적 성취는 학교급별로 평균의 차이가 있었는데, 중학교와 고등학교는 차이가 없었으나 초등학교와 중등학교 간에는 차이가 있었다. 또한 학교급 내에서 남녀 차이가 있었는데, 대체로 남학생의 정의적 성취가 여학생보다 더 긍정적이었다. 인지 진단 이론에 의해 학생들이 성취한 정의적 속성의 비율을 학교급과 성별로 살펴보았을 때, 중학생이 자기 통제와 불안을 가장 많이 성취하고 있었고, 모든 학교급에서 가장 많이 성취한 속성은 수학에 대한 가치 인식이었다. 학교급 내 남녀 학생들이 성취한 속성의 수를 살펴보면, 모든 학교급에서 남학생이 학습지향성, 흥미, 자신감을 성취한 비율이 여학생보다 높았고, 여학생들은 불안이 있는 경우의 비율이 남학생에 비해 높았다. 학생들의 개인별 프로파일을 보면, 불안은 없으면서 나머지 5가지 속성을 모두 성취한 학생들의 비율이 가장 높았다.
